species of Cumulus
Strongly sprouting Cumulus with generally sharp outlines and often great vertical extent. The bulging upper part of Cumulus congestus frequently resembles a cauliflower. Cumulus congestus clouds may produce precipitation; in the tropics, they often release abundant rain in the form of showers.
Cumulus congestus clouds sometimes resemble narrow, very high towers. The tops of these towers are formed of cloudy “puffs”, which may detach themselves successively from the main body of the cloud. They are then carried away by the wind and disintegrate more or less rapidly, occasionally producing virga.
Cumulus congestus results from the development of Cumulus mediocris, or sometimes of Altocumulus castellanus or Stratocumulus castellanus.
Cumulus congestus often changed into Cumulonimbus; the transformation is revealed by the smooth appearance or by the fibrous or striated texture of its upper portion.
